GAS-BURNING ATTACHMENT FOR COAL COOKlNG-STOVES.

SPECIFICATION forming part of Letters Patent No. 729,233, dated May 26,1903.

' Application filed January 29, 1903. Serial No. 140,964. (No model.)

To (tZZ whom it may concern:

Be it known that I, HENRY C. STEINHOFF, a citizen of the United States,and a resident of the town of Union, Hudson county, New J ersey, haveinvented certain new and useful Iniprovements in Gas-Burning Attachmentsfor Coal Cooking-Stoves, of which the following is a specification.

This invention relates to an attachment by means of which the ordinarilyinactive potholes of a coal stove or range, above the oven, may bereadily utilized for gas cooking purposes.

In the accompanying drawings, Figure lis a front elevation of acoal-range provided with my attachment; Fig. 2 is a plan of theattachment, and Fig. 3 a vertical central section on line 3 3, Fig. 2.

The letter (L represents a coal range or stove of suitable construction,a being the top plate and a one of the pot-holes above the oven a Belowthis pot-hole is centered the nozzle 1; of a gas-pipe l), which issupported, preferably, upon the roof of the oven, Fig. 1.

The pot-hole a is adapted to receive the shell 0 of my improvedgas-burning attachment. pot-hole and is provided .with a circumferentialflange c, by which it is suspended from the top plate a. The shell 0tapers from top to bottom and is provided at its bottom with anupwardly-projecting perforated coniform flange 0 which snugly embracesthe nozzle 1), to form a tight joint.

Upon the shell 0 is supported by arms or lugs d an annular top plate d,having depending flange (Z between which and the shell an annularair-space or outer downtake-flue e is formed. From the plate d projectinwardly a number of radial ribs (1 the inner ends of which are arrangedabove the top of a Bunsen burner f, having usual lower air-holes f. Thedrawings show the burner made This shell is of a size to fit within theintegral with the ribs (1 which is the pre ferred construction, thoughobviously the burner may also be supported by the shell 0. The ribs (Zserve to support the cookingutensil and bridge the annular space orinner uptake-flue g, between flange d and burner f. The flange d extendsto a point above shell 0, so as to divide the flue c from the flue gwithinthe upper part of the shell.

In use the attachment is set into the pot hole a so as to be supportedby the top plate a, when the flange 0 will come into prompt engagementwith the nozzle 1). The air necessary for combustion will be fed to theairholes f of burner f through the outer downtake-flue 6, while theheating gases radiatin from the burner will reach the cooking vesselthrough the inner uptake-flue g.

It will be seen that my improved attachment is so constructed that it isreadily fitted in place and that it gives off a large volume of heat. Bymeans of the attachment the ordinary inactive potholes above the ovencan thus be readily utilized for gas-cooking purposes.

What I claim is- 1. A gas-burning attachment for cookingstoves providedwith a shell, an inclosed burner, and a top plate having a dependingflange between shell and burner, substantially as specified.

2. A gas-burning attachment for cookingstoves provided with a shell, aninclosed burner, and a top plate having a depending flange between shelland burner, and radial ribs that project over the burner, substantiallyas specified.

Signed by me at New York city, (Manhattan,) New York,this 28th day ofJanuary, 1903.
